Once you decide to start your crypto trading adventure, one question always comes to mind – where should you do it? Should you choose a leading exchange just for its popularity, or would looking for one with lower fees be better? Is security your primary concern, or is it the products an exchange offers?

In this situation, some names might be found among your options, and will probably be one of them. If this is the case, it’s time to learn as much as possible about this platform and potential issues that might appear when trading crypto on

In this article, we will discuss the “Declined by Card Issuer” error, an issue many users deal with occasionally.


Launched in 2016 in Hong Kong, is one of the most popular crypto exchanges, being in the top 15 platforms by trading volume. The platform gathers approximately 80 million users from over 100 countries, including the US, the UK, Australia, and numerous countries from Europe, Africa, South America, and Asia.

On, users can purchase, sell, and trade more than 250 cryptocurrencies, including the most popular, such as Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Tether (USDT), Dogecoin (DOGE), Cardano (ADA), Polkadot (DOT), Polygon (MATIC), and Litecoin (LTC).

Furthermore, the platform also developed its coin, called CRO. Those holding CRO can get lower trading fees, higher staking interest rates, and higher credit card rewards.

Many users might consider that the fees charged by are pretty low, and we can see why. If you are a new user and do not hold CRO tokens, you will have to pay a fee of 0.075% on trades with a monthly trading volume of less than $250,000. If you aim to trade more than that, the fees can reach 0% for makers and 0.05% for takers (if you don’t have CRO tokens).

On the other hand, if you hold a minimum of 1,000 CRO, you will have lower trading fees. In this situation, the 0.075% fee we mentioned earlier will transform into a 0.0728% fee.

To trade crypto, you first have to purchase it, and in’s case, you can do it with a credit or debit card as a payment method. But what do you do when you encounter a card decline situation?

Well, there are some reasons why this might happen, and the good news is most of them also have at least 1 way to fix them.

The App Is Not Working Properly -> Check Internet Connection

One of the top reasons users’ debit cards are declined when trying to buy crypto is the app not working at that moment. It can be a problem with your device, internet connection, or account, a bug in the app, or scheduled maintenance.

If the app is not working because the team is working on it or has to discover and resolve a bug, you usually just have to wait.

Of course, if you get the same decline message for a more extended period and are sure that everything is working well on your side, you can contact the support team to learn more about the issue.

On the other hand, if something is happening with your app only, there might be a problem with your device or internet connection. In this case, you can check the internet connection and try to discover where the problem is. Furthermore, you can try to restart your device.

You Don’t Have Enough Funds -> Top up Your Account or Change Card

If the app and your phone are working well, but your card is still declined during the payment verification process, you should try to check your balance. You may have insufficient funds on it or have reached the credit limit in a credit card case. If you want to use a specific card and it does not have enough funds, you can fix this problem by making a bank transfer.

Furthermore, you might want to check your card’s expiry date, as you cannot use a card if it is expired, be it a credit or debit card. If this is the problem, you can change the card you want to use for buying crypto to not have declined transactions.

If you aim to use the same card (e.g., you have a card you usually use for crypto), contact the issuing bank and ask it to change your card.

After you ensure that everything is under control with your card, you can retry funding your account.

There Are Credit or Debit Card Errors -> Check Card Details

If you still cannot complete the transaction and you get the same error message, there is a slight possibility that you might be a fraud suspect.

In this case, things get a little more complicated, and there is not much you can do to resolve this issue immediately.

In this situation, we highly recommend contacting the card-issuing bank and discussing this issue. If nothing is wrong with your account and activity, the error might be fixed quickly.
